When consciousness is forcibly dragged into a strange space called the "Gap", each participant becomes a "walker" struggling on the edge of life and death. Su Yan, a former criminal investigation consultant, has logic as rigorous as a scalpel, but is burdened with an unspeakable past in the real world; Lu Yan, a mysterious freelancer, is not as agile as ordinary people, but there is an alienation in his eyes that is incompatible with this world.
They met in the first mission world "Scarlet Theater". One relied on reasoning to dismantle the rules and traps, and the other used intuition and force to tear apart a way out. The two people who were forced to form a team grew from being wary of each other to gradually trusting each other. The world of "Boundary Gap" is eccentric, ranging from apocalyptic cities besieged by zombies to serial murders in ancient houses, from future ruins with out-of-control supernatural powers to a theocratic kingdom that requires sacrifice of faith. Each world has its own cold rules, and violators will be completely swallowed by "Boundary Gap".
As the mission progresses, they discover that the existence of the "boundary gap" seems to be closely related to certain disappearances and unsolved mysteries in the real world. The secrets of Lu Yan and the shadow of Su Yan's past also gradually surface in the life and death tests. Is it a chess piece controlled by the "gap", or a variable that breaks the cycle? Only when two lonely souls stand back to back can they hear the weak but firm echo of each other in the endless reincarnation of the world.
Intention: growth
